To all whom it my concern.:

Be it known that 1 HARRY HU'rC'mNson,

' a citizen of the United States, and a resident of Syracuse, in the county of Otoe and State of Nebraska, have invented an Improved Tool for Use in Oiling Leaf-Springs, of which the following is a specification.

My invention is a hand tool 'for separating the leaves of elliptic or semi-elliptic carriage springs suiciently to permit the introduction of oil or other lubricant between them for the purpose of relieving friction between the leaves and enabling them to slide easily on each other.

Tlie.details otconstruction and operation of the tool are as hereinafter described, and illustrated in the accompanying drawing, in which- Figure 1 is mainly a longitudinal section of the tool, the same being shown applied to a leal:l spring shown in cross section. Fig. 2 is a plan or edge view of the tool.

The body or frame 1 of the tool has two lateral bends or recesses arranged side by side, the larger one being adapted to reeeire a leaf spring, as indicated in ltig. il. 'lhe frame 1 has a rigid handle extension 2 whieh is practically in alinelnent with it. other handle 2l, arranged opposite the handle 2, is pivoted at t at the rear end ot" the frame 1 and provided witlan inwardly projecting lng 5 which is adapted to bear against the flanged head of a pin or rod (t that is held slidably in. perforated lugs T on the frame and which traverses the, smaller recess arranged in rear ol the larger one before referred to. A spiral springr 8 encircles the portion of the pin (i which traverses the smaller recess, and which presses against a collar (la which is fixed on the pin. The result of this arrangement and connection ot' parts is that the spring holds the pin 6 normally retracted and pressed against; the short arm of the handle The latter is, however, extended forward of the The i pivot, as indicated at tl, and bears against the rear lug 7 ot the 'li-ante, which prevents the handles separating too widely. A. pointed screw pin ttl is arranged in the outer end oit' jaw 11 of the tranne and opposite to and in alinenient with the opposite pin (i.

In practical use, the recessed portion ot' the frame 1 is placed over a series of leaves comprising a carriage spring, the screw pin 10 having been retracted sulliciently for this purpose. Said pin is then rotated to force its point into Contact with the spring, that is to say, into the groove between two leaves which lie in cont-act'. Then, by compressing the handles 2 and 3, manually, pressure is applied to the pin 6, thus causing both pills t3 and 10 to wedge between adjacent leaves of the spring and force them slightly apart, or sutlicicntly to permit. the introduction o'l oil or other lubricant. Upon rel easing the pressure on the handles, the. slidable pin G is ret 'acted and pressure on the spring relieved.

YWhat l claim is The tool for use in citing leal" springs, comprising a frame having a handle extension and two lateral recesses, the larger recess being adapted to receive a leaf spring, a pointed screw piu arranged in the outer jaw o'l the traine and its pointed end projecting into the larger recess. another pointed pin arranged slidahly in the frame opposite to and in aliueinent with the screw pin and tra rersing therslnaller recess of the traine. a spiral springeneircling such slidable pin within said reeoss. and a movable handle pivoted to the traine in rear of the slidahle pin and provided with an inwardly projecting lug adapted to bear against said pin7 as described.
